Why Rymax Endurox LD 10W-40
Semi-Synthetic Base Stocks
Superior thermal and oxidation stability versus mineral 15W-40. Better film retention under high-temperature turbocharger conditions — protecting engine components and extending the practical drain interval.
Extended Drain Capability
Semi-synthetic formulation resists breakdown longer than mineral oils — reducing total oil consumption, waste oil disposal costs and maintenance downtime for mixed diesel fleets.
TBN & Acid Neutralisation
TBN of 10.5 mgKOH/g sustains acid neutralisation capacity through the full drain interval — critical for South African fleets operating on higher-sulphur diesel.
Soot Dispersancy
Superior detergent and dispersant system prevents soot agglomeration and piston deposit formation — maintaining engine cleanliness and oil pumpability from cold start to oil change.
Anti-Wear Protection
Excellent anti-wear, anti-corrosion and anti-foam properties protect bearings, camshafts and cylinder liners under sustained high-load operation.
Broad OEM Coverage
Comprehensive OEM approval portfolio covering major European and American truck manufacturers — one product for an entire mixed diesel fleet.
Recommended Applications
Long-Haul Transport
Heavy-duty diesel trucks requiring extended drain intervals. Semi-synthetic base reduces oil consumption on high-mileage long-haul and regional distribution operations.
Mining & Construction
Haul trucks, excavators and earthmoving equipment in high-dust, high-load environments across the Northern and Western Cape.
Bus & Coach Fleets
Euro III-V bus engines from Volvo, MAN, Mercedes-Benz and Scania. Broad OEM coverage simplifies procurement for mixed municipal and intercity bus fleets.
Agriculture
Tractors and harvesters from European and Japanese manufacturers operating on both low and higher sulphur diesel across South African farming regions.
Industrial Power Units
Stationary diesel generators and compressors requiring robust oxidation resistance and acid neutralisation for continuous-duty operation.
Mixed Fleet Operations
One semi-synthetic oil covering an entire mixed diesel fleet — simplifying lubricant procurement and reducing SKU complexity.
